ABSTRACT
  Al6082-T6 is widely used because of its corrosion resistance and excellent strength. HAZ softening occurs in MIG welding process for this aluminium alloys because this aluminium alloy is heated to higher temperature than its aging temperature during welding. Therefore, low heat input and minimum standard deviation of heat input are required for narrow HAZ width and, for higher strength of welds. In this study, Al6082-T6 was used to examine for HAZ softening with various heat input in aluminium MIG welding. For weldments, micro hardness was measured and tensile test was carried out. Minimum hardness was increased at high speed welding such as 80㎝/min and 120㎝/min in welding speed comparing with 40㎝/min. Also, in case of high speed welding such as 80㎝/min and 120㎝/min, tensile strength of weldments was increased about 10% comparing with low speed welding(40㎝/min).
